Toall whom it may concern: v 3

Be it known that I, CHARLES A. L. Bacn, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia. 'and State of Pennsylvania, have invented certain new and useful Improvements in litoller-Bearings, of which the following is a specification.

invention relates to the provision of {anti-friction bearings for general application, and the invention consists in certain ullar novel details ofconstruction hereafter-fully described and claimed and illustrated in the accompanying drawings, in which:

Figure 1 is a vertical transverse section substantially on the line 11 of Fig. 2,v illustrating the invention as applied to a sta- I tionary axle surrounded by a' rotating hub or Wheel; Fig. 2 is a fragmentary longitudinal section on the line 2 2 of Fig. 1 F 3 isaplan view of a modified form otthe init; Ll

Yention, one of the bearing plates being removed, and Fig. 4 is a sectional View of the same modificati n corresponding to the View in Fig. 2. v Throughout the following description and on the several figures of the drawings similar parts are referred to by like reference characters.

Referring particularly to Figs. 1 and 2, at 10 is indicated a cylindrical spindle of a stationary axle about or upon which the bearing is to be employed. It is to be understood however that is contemplated. that the spindle and easing surroiuuling the same maybe related to each other ditlercntly from that above described in that the easingmay be astationary box and within which the spindle may rotate as in the case of a car axle or a rotating line shaft, or inachincry bearings generally. The casing or boxing 11 is shown as in the fol-in of a hot-- low cylinder having a bearing track or surface 12 opposite the spindle 10 and the edges of which trash: 12 are formed withda' sions or grooves-12f terminating in inix'ardly projecting flanges 13. At each end of the boxing 11 is an inclosure plate 1 1, the plates being connected to the boxing in any suitable manner, such for instance as by screws 15, whereby the boxing l1. and the end plates tion rollers may be interposed between the as to avoid rubbing contact.

may be of any suit-able configuration with in the spirit of this. invention. As indicated however a series of smaller rollers 15 sur- 50 rounduand contact the spindle 10, but the said rollers are spaced from one another so Each of the rollers 15 is provided with rounded orspherical ends 15 which cot perate with shoulders 16 and 17 on the spindle. The shoulder 16 consists of a nut screw threaded upon the end of the-spindle and abutting snugly against a shoulder 10. T he nut is also provided with a curved raceway 16 ad- 70, jacent to said roller for cooperation with the ends 15 of the rollers. The not is substantially circular at that portionv extending through and into the casing, but is provided upon its ot er end with a polygonal portion 16 for the application of an ordinary wrench. In order to present a finished ap pearance and prevent obstruction or injury the said nut is inclosed by means of a me--- tallic cap 18 screw-threaded at 18 to the nut. A gasket 19 may if desired be interposed between the nut and the adjacent edge of the end-plate 14 for the purpose of excluding dust, dirt, or moisture. -The shoulder 17 is screw-threaded by means of threads 17 of any suitable character upon the inner end of the spindle, and said shoulder 17 may be movedlengthwise of the spindle, by virtue of said screw-threads, if it.

is desired to adjust the-bearing. The shoul- 'dcr 17 is substantially cylindrical on its outer surface and may be provided with sockets 17 for the application of a spanner if desired for the purposeof adjustment. It is provided at its inner endalso with a raceway 1T correspoinling to the raceway 1(3 aforesaid and for a similar purpose. A gasket 1!) may be employed in cmmecition with this shoulder in the manner above sug-' gested with reference to the nut 16. The spindle furthermore 'is provided with a screw-threaded portion 20, the threads of which are of an opposite character to the threads 17, and upon which a lock nut -21 is adapted to abut snugly against the inner 165 end of the nut- 17 and lock itfrom displacement.

At 22 are shown a series of larger rollers, of the same nurnberas are used of the rollers 15 and, whereby the said rollers'lo are spaced from one another and maintained in proper. operative relation to the spindle.

By reason of the fact that the rollers 22 are larger 1n diameter than the inner rollers 15 3 said inner rollers are positively prevented from passing between the outer rollers and escape from contact with the spindle. I

have found in practice that in previous devices of this character where the inner rollfore that theedges of the heads cotiperate with the grooves 12' of the cylinder 11. It

will be seen from the 'camstruction hereinbefore described tliatnot only will the reladers of the moving parts.

.tive side thrust between the shaft and boxingbeftaken by the sets of rollers but also any tendency for end thrust will be counteracted by'the cooperating flanges and shoul-v That form of the invention illustrated in Figs. 3and 4 is verysimilar'in most respects to the form above described in that there are provided two bearing members, one of which is movable with respect to the other, and between which. bearing members are interposed a plurality of sets of antifriction rollers. In this form of the invention however the two relatively movable bearing members are an upper disk 23 and a lower disk 24. Said-disks are arranged substantially parallel to each other in horizontal planes and the one of which is movable 9 around a central axis with respect'to the 'othe r dislg'said axis being vertical. This type of the invention is especially applicable in connection with car trucks and other formsof vehicles in which a central bolt is employed-to connect the car or vehiclebody to asupporting truck. In this instance a king bolt is indicated at 25 and. with or around which" one of the disks rotates'with respect to the other. As in the former .instance the interposed antifriction rollers comprise a series of smaller rollers 15 hav-' ing spherical or rounded ends, a series of larger rollers 22, having enlarged ends or, headsbetween which the smaller rollers operate'. Byreason of the fact that the rollers in this type of hearing are arranged radially important that the'rollers shallibe tapered orjffirusto-conical.- The upperdisk .23is I with respect to the axis orkingbolt it is the opposite-ends of said provided with raceways 006 with the ends of the upper rollers 15", and the lower disk 24 is' provided with grooves and flanges corresponding to the grooves 12 and flanges .13 of the above described casing, whereby end thrust upon the rollers will be resisted by cooperation of the rollers and or dimensions of'the several parts.

Iclaim:

1'. The hereindescribed roller bearing comprising, in combination, two relatively movable bearing members one of which is provided with a pair of raceways and the other of which is unitary and provided with a main bearing surface, a pair of spaced grooves, and a pair of flanges constituting raceways, aseries of spaced rollers cooperating with one of said bearing members and having spherical ends cooperating with the first mentioned raceways, and a series of said 'raceways an having enlarged end heads between w ich" the first mentioned larger rollers co'tipzgrating with the other of rollersfiperate and which heads extend into and cobperatewith said grooves and flanges of; the second mentioned bearing member, roller heads being spherical. v I 2. The hereindescribed roller bearing comprising, 'in combination, an axle having a shoulder, a nut screw-threaded upon said axle 'andabutting snugly against said shoulder, the adjacent-end of said .nut constituting a raceway, a sleeve on said axis spaced from said nut and adjustable toward and from the same, .one end of said sleeve constituting another raceway, a series of rollers cooperating with said axle a'ndiwhoseends cooperate with the said raceway, and a hollow bearing member surrounding said axleand provided with a smooth-bearing surface alo'ng the edges of whichare formed ,a pair of grooves and inwardlyextending flanges, and a series ofilarge-rollers cooperating with said hollow bearing member and having enlar ed heads extending into and cooperating with said grooves and flanges, said heads being spherical on their outer ends and between which heads theaforesaid round ended rollers are e1nbraced,'substantially as set forth.-
